[SOLVED] TerraTec Driver Issues

Hi,
I got from my mother a Video Capture Device called TerraTec Grabby. I'm not sure wether this is right in the media channel, because it could touch kernel/hardware a bit more.
According to this wiki[1] it should work out of the box with a "current" linux kernel.
The Company offers "Linux Drivers"[2] as well, but I looked into it and found out there is an AUR for it. So I installed v4l-dvb-git from the aur. But it still didn't worked.

What I want to do is simply to capture the input form the Device with vlc or mplayer and store it to a file.

So I tried this command:

$mplayer tv:// -tv driver=v4l2:width=720:height=576:device=/dev/video1:input=0:fps=25:norm=SECAM-L:alsa:adevice=hw.2:audiorate=48000:forceaudio:amode=1:immediatemode=0
MPlayer SVN-r37857 (C) 2000-2016 MPlayer Team
224 audio & 451 video codecs
do_connect: could not connect to socket
connect: No such file or directory
Failed to open LIRC support. You will not be able to use your remote control.

I think there is something wrong with the sound. But I couldn't put the finger on it.

"dmesg" gives me the following. Looks allright

lsusb gives me the same as in the wiki[1].

Re: [SOLVED] TerraTec Driver Issues

I haven't fiddled around at all just kept updating my system. Now with the new kernel it seems to work. No idea what was wrong.
